WZLLIAM F. POTTER, OF ELMIRA, NEW YORK.

AUTOMOBILE SIGNAL LAMP.

Application filed March 23,

T 0 all whom it may concern Be it known that 1, WILLIAM F. POTTER, a citizen of the United States, residing at Elmira, in the county of Chemung, and State of New York, have invented certain new and useful Improvements in an Automobile Signal Lamp; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the same.

The object of the invention is to provide simple and eihcient, means to serve as a guide to indicate the position and direction of movement or" an automobile or simiiar motor driven vehicle with the object of minimizing accidents incident to uncertainty as 'to position and direction of movement on dark roads, and also adapted to serve as a suitable parking light and generally to serve as a means of minimizing the likelihood of accident incident to the use of vehicles of the indicated type; and with these objects in view the invention consists in a device of which a preferred embodiment is illustrated in the accompanying drawing, wherein:

Figure 1 is a view of a lamp embodying the invention applied in the operative position to a vehicle.

Figure 2 is a longitudinal sectional view of the lamp including a diagram 9f the nor in% system. he lamp iii-general construction preferably embodies a relatively elongated casing 10, provided at its front and rear ends with lenses 11 and 12 in rear of which are arranged lighting units 13 and 14 preferably consisting of incandescent electric light" bulbs served by and arranged in circuit with the lighting system of theautomobile or car in connection with which the device is used, the lead wires 15 and 16 in connection respectively with said lighting units having independent controlling switches 1.7 and 18. The casing is provided with a suitable clamp adapted for attachment to a convenient portion of the vehicle, and the device is designed particularly to be applied to the vehicle at the left side and near the front, as upon the forward left hand wheel guard as shown in the drawing, with the length of .the casing disposed parallel with the direction of movement of the car and with the said casing, and each on a di 1921. Serial No. 454,652.

lenses 11 and 12 respectively directed forwardly and rearwardly.

The forward lens is preferably green and the rear lens yellow, so that whether the car is progressing and the lamp is being used as a running light, or is stationary or parked, the forwardly directed rays of green light serve to indicate the position of the car which, in accordance with the well known and recognized nautical rules must always be to the right of the green light as viewed by an observer facing the same, if the vehicle is approaching. The forwardly directed green light may and is preferably used, not only as a running light but as a parking light and the rearwardly-directed light is preferably used only for parkin pu ses and for this reason should as a ove mdicated be controlled by a aseperate switch.

In the preferred embodiment of the device the casing 10 is divided into front andrear compartmentsb a transverse partition 20 to which thesoc sis-21 of the 'ghting units 13 and 14 are attached as a convenient means of arranging the same in the proper position centra ly in the casing, and the clamp or means for attaching the device to the vehicle may consist of the tubes 22 headed as at 23 within the cylindrical wall of the casing and exteriorly threaded for engagement by the inner and outer. nuts 24: and 25 for arran ment respectively'above and below the wieel guard 26 or similar portion of the vehicle to which the lamps may be attached, said tubes which also act as fastenin bolts, serving as convenient conduits t rough which the lead wires 15 and 16 are extended to the lamp sockets, as indicated clearly in Figure 2 of the drawing.

Having thus described the invention, what I claim A signal device rovidedwith a casing,

removable closures or opposite endsof said casing, said casing having a transverse pnrtition therein and integral therewith, sockets secured to and extending from o posite sides of said'partition, a lu-rality 0 signal 1 2'- means disposed one in eac socket, a plurality of tubes depending through 0 emngs in rent .sidoof said, partition,said .tube's hai ing retaining heads disposed within the casing below and in spaced relation to the ss said tubes being exteriorly screw threaded, nuts the other tube to turn therefrom as a fuloperable on the threads of said tubes to 0mm.
